Nonsyndromic craniosynostosis (NSC) may manifest with complex behavioral, attentional, and emotional sequelae. We characterized higher-level brain connectivity in adolescent NSC patients in response to emotional frustration.
Surgically corrected patients age >9 with NSC were age/gender/handedness matched to controls. Patients participated in a GoNoGo task, structured as "win/lose/recovery" paradigms; "Win" allowed point increases, "lose" led to net negative points, and "recovery" allowed re-accumulation. BioImage Suite was used to analyze whole-brain intrinsic connectivity between tasks with cluster-corrected group-level T-maps. P<0.05 was significant.
Seven unilateral-coronal (ULC; average age 12.2 years), six metopic (average age 11.5 years), and respective matched controls were included. ULC had worse emotional regulation scores on the Behavior Rating Inventory of Executive Function survey(p=0.065) and performed poorly on the GoNoGo task(p<0.001). Metopics had four regions of interest (ROI) with majority decreased activity compared to controls, and few differences between tasks. ULC had eleven ROIs, majority decreased during "win" and "lose", but all increased during "recovery". Metopic patients had decreased blood-oxygenation-level-dependent signal in the posterior cingulate(p=0.017) and middle temporal gyrus(MTG;p=0.042). ULC had decreased signal in the posterior cingulate(p=0.023), MTG(p=0.027), and thalamus(p=0.033), but increased signal in the cuneus(p=0.009) and cerebellum(p=0.009). R-ULC, but not metopic/controls, had increased right brain activity in the caudate(p=0.030), thalamus(p=0.011), temporal lobe(p=0.012), and cerebellum(p=0.029).
ULC patients may have emotional dyregulation in response to frustration while metopic patients may have attenuated emotional reactions. Evidence of R-ULC brain laterality suggest that the area of suture fusion may contribute to the mechanism of dysfunction.
